The construction offthe-platformdli, shown in the drawings, will be dealt with hereinafter, but I changes in the depictedform of the" platform e made, without departing from the spirit of the invention. I I Assuming that, in Fig. 2, the' part of the vessel thatis designated by the numeral I8 is disposed I toward [the bow, the platform JIG" may be said to comprise a' forward transverse beam'IQ, an after transverse beam 20, and an intermediate transverse beam 2 I-. Thepivot elements I1,;which supportthe platform It for vertical tiltingmovement, are engaged in the beams 20, 2I and I9.

I A forIe and aftoatwalk or tread 22 is'secured rigidiy to t he outboard ends oi the beams I9, H and, 20.. A guardrail structure 23 extends longitudinally ofthje outer edge of the tread zz and I along the ends thereof and is carried by the tread andthe beams I9, '20 and 2I. On its inboard The cabinis designated bythe numeral] and the 1 overhang 50. I I E Rigid da vits t; are supplied, and ar pivotallv mounted at 1; at their lower ends on'thesparj deck 2,. to swing inboard and outboard; inparallel; thwartship planes. The boat is marked by the numeral 8, the keel thereof appearing at 32,

the boat being connected to the upper portion roofcof 'i'tconstitut'es a boat deck 5 having an screwalegs 25 prevent thewheels 29 from coming side; the guard rail 23is open, to give access to {the boat 8, when the boat; is on the boat deck 5.

Loop s'hapedhousings or guards 24 are secured to the inner ends of the platform beams 20, N and I9. Screws 2 5 are threaded into the lower portionsof the guards 24, and are supplied at their upper ends with any suitable manipulating.

means, ,such as hand wheels 28, abovewhich the guards '24 extend. The lower ends. of the screws 25 :areadaptedto rest on the boat deck 5, and I constitute adjustable legs for disposing,

45 form I6 parallel to the boat deck. I

A supporting sni er is secureclto the platform beam Z I'and extends-lengthwise thereof, in spaced relation thereto. l The strip 21 and the beam'ZI carry axles 28, wherecn anthfriction devices 29,

such "as wheel sfaremounted to rotate. The

" intocontact iththQ'bOat deck '5. The Wheels '1 lsjarefimounted to rotate on fore and aft axes,

represented by the parts"28. Th intermediate platform beam H is somewhat longer than the l the plat- I I fore and aft beams It and 2e, respectively, 'inorder to accommodate the line of wheels 29.

Saddles 39 rest on the boat deck 5, removably, and support the boat 8. The inner ends of the" 'siddles 39 are spaced aparta little, as shown in Fig. '2, at 3|, so that the-keel 32 of theboat may come into contact with the beams l9-2l2i.

The construction is such that, when the boat 8 is injplace on the saddles 30, as shownin Fig. 1, the lower edge of the keel32 will engage the beams 28,21 and t9, and, thus, the boat'serves tq'illd r the platform iii in the horizontal position of Fig.

, theiboat untilit'rests t re inner" portion of the r 7 platform, thereby to hold the platform in approximately horizontal position, with the out 1, it beingpossible-fo-r persons to occupy the, tread 22, for any useful purpose.

The inhaul tackle 5! for the davits f5 iorin sn o part of the present invention, and may be con-Iv structed as desired. By means of theblock and falls 9! ii, the boat is raised, andlsincethe platform it is freed the weight of the boat, the plat-.

form swings outboard. When the davits' 6 are' swung'cmtwardlmzthe,boat 8 is carried outwardly forllowering away. .The pivot elements-ll are easily removable; to permit the platform ltto of the boat and thebeams 21 of the platform It,

overhanging davits 33 are employed, in the place ,of the straight davits- E,- the' standards .of the 1 be hauledinboard, so as not to foulother vessels, .docks,,etc.,-in close quarters. a When the davits 6 and the boat ii areswung V outboard or inboard, the wheels 29 prevent an objectionable rubbing contact between the hull davits being mounted in any conventional way,

at 36, on the spar deck 2a, or elsewhere, tor

tate about vertical axes; The fore andaft thwartship beams lilo and 29a of theplatform [5a, respectively, do not overhang the boat desk to, as do the beams IS andZe of Fig. 2, but have their inner ends pivotally'connected to the edge of the boat deck 5a, by means of the brackets l5d', the w s Z Theintermediate beam} I a of the platform. 5a overhangs the boat deck- E05 and carries a thwartship, elongated-roller 35, journaledat 3% on the beam 21d. and extended longitudinally thereof. The roller 35 replaces the wheels 29 of Fig. 5, an ma be found more convenient'than those wheels,

since, when the davits 33 are employed, the boat their inner ends secured to the intermediate beam am, the outer ends of the bracesbeing secured'to the platform beams 26aand iSa,

, The operation of the device shown in Figs. 5

and 6 does not difier materially from the operation of the device shown in the remaining figures,
